1.From the days of the Egyptian and Mesopotamian empires, people have valued dogs because many of their senses are much stronger than ours.
A dog’s sense of smell is keen, as can be seen in the fugitive-hunting activities of the bloodhound. A dog’s sense of hearing is acute, especially for high-pitched sounds. Though dogs are nearsighted and colorblind, their eyes can detect the slightest movement.

2.In far-off days, dogs first served people as hunters. Mesopotamian records from 3000 B.C. describe greyhound-like dogs. Labrador retrievers, Irish setters, and Russian wolfhounds are a few descendants of early hunters.

3.Work dogs also have a long-lived history. German shepherds, English collies, and Siberian huskies belong to the hard-working group.

4.Today, most breeds, such as the Yorkshire terrier, the Mexican chihuahua,
and the French poodle, are kept mainly for companionship.
